Question 748267: Tim and James started riding their bicycles together from the same location at the same time, going in the same direction. Tim's rate of speed is 8 mph, and James's rate of speed is 6 mph. How long will it take for Tim and James to be 10 miles apart? What do the constant and coefficients represent in the equation? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! D=RT
D+10=8T OR
D=8T-10 FOR THE 10 MPH BIKER.
D=6T FOR THE 5 MPH BIKER.
SET THE DISTANCE EQUATIONS EQUAL & SOLVE FOR T.
6T=8T-10
6T-8T=-10
-2T=-10
T=-10/-2
T=5 HOURS ANS.
